This property sheet designates which user accounts have operator permissions for the SMTP Site. After Microsoft Windows NT accounts are set up, you can grant permissions by selecting the accounts from a list. Removing the account from the list of site operators will rescind these permissions.

Use this property sheet to set limits for messages, including size and number of recipients. If a message exceeds the limits you designate, it is undeliverable and will be returned to the sender along with a Non-Delivery Report (NDR). If the NDR is also undeliverable, the message is sent to the Badmail directory, since the message cannot send or returned. You can use this property sheet to designate the location for the Badmail directory in addition to storage for NDRs and bad mail.
